Patent DE-2137438-A1 (DE)
Title: Double element filter - with automatic changeover system for regeneration
Inventor: SCHAEFER JOHANNES DIPL ING DR
IPC: B01D35/12
Filed: 1971-07-20

Title: Needle positioning - in industrial sewing machine by logic circuits and photo-transistors
Inventor: SANGIORGI MARIO
IPC: D05B69/22
Filed: 1972-06-20
Abstract: The operator selects the control function desired, and the light sources, with the pre-set blanking of the light port and the phototransistors determine the logic circuit to be employed together with time delays. The selection provides for the drive shaft to be re-coupled to a slow drive motor, for the needle to be held at the top or bottom dead centre posn and for the thread cutter to be operated. The purpose is to give the operator needle control when seaming is completed.

Patent DE-2239138-A1 (DE)
Title: Hot impregnation of porous foams - including heat-sensitive foams and removal of excess impregnant under vacuum, coating walls of pores
Inventor: SCHROETELER GEORG
Filed: 1972-08-09
Abstract: Open-celled or porous foam bodies, esp. sealing strips are impregnated with a liquefied impregnant and freed from excess impregnant under vacuum; the vacuum is such that when using impregnants which have been liquefied by heating the temp. at which the impregnant becomes liquid is lowered. Suitable impregnants are bitumen, wax, synthetics, rubber pitch and viscous oils. Excess impregnant is removed by squeezing, centrifuging or suction, so that only the walls of the pores are coated with impregnant and the pores are not filled. Removal of air from the pores facilitates penetration of the impregnant into the foam and the process is quicker. The impregnant is liquefied at a lower temp. under vacuum, making it possible to impregnate heat-sensitive foams. A wider range of impregnants can be used.

Title: Injection mould for thermoplast bottles with automatic centering - by two cones meeting at base of mandrel
Inventor: BEYERLEIN LUDWIG
IPC: B29C45/27
Filed: 1973-08-01
Abstract: An apparatus for injection moulding a hollow objects comprises a mandrel and a mould fitting around the mandrel, each of these is mounted upon a support plate, the plates being movable relative to one another to bring the mandrel into the mould. At the base of the mandrel and at the free end of the mould, there is a centering cone; the injection mould is free to slide relative to its support plate along a path perpendicular to the axis of the plate; when these two cones come into contact with each other, a releasable locking device, esp. a hydraulic or pneumatic piston, is released permitting the mutual sliding between the mould and its support plate; when the cones are out of contact, the switching mechanism automatically maintains the mould locked relative to its support plate. Esp. for moulding thermoplastics bottles intended for containing pressurised drinks, esp. gasified drinks. The arrangement enables automatic centering to be carried out, thus ensuring that the axes of the mandrel and mould are absolutely coaxial.

Title: Variable-length coil - has wire wound on cylindrical body with contact pins and legs beyond end flanges
Inventor: SACHSSE LOTHAR
IPC: H01F37/00
Filed: 1974-01-07
Abstract: The variable coil, such as a wire-wound resistors or choke, has a cylindrical body along which the coil wire is wound. The ends of the wire are led up over the two end flanges to contact pins protruding up out of the cylindrical body on the outside of the flanges. These contact pins pass through the ends of the body and downwards to form contact legs. Each end of the coil has three contact pins and three closely-spaced contact legs. The tops of the flanges are curved and the bottoms flat for mounting. The body may, however, have shapes other than cylindrical. The advantage of the coil ies in the simple manner in which its length may be altered.
